Uptake Mechanism of Different Photosensitizers in Fibrosarcoma Cells, Fibroblasts and in Epithelial Cells
Several photosensitizing dyes with different photochemical and photophysical properties have been developed and have caused considerable interest for use in photodynamic therapy . Beside the photochemical and photophysical properties, the abilitiy of accumulation in the tumor, the distribution in the cells and the ability to produce cytotoxic agents are the key factors determining the efficiency of the therapy.
